折叠纸盒锁底结构承载力实验研究

目的研究锁底结构形式对纸盒承载力的影响。方法选取3种常用的锁底结构(插口式、1-2-3锁底式、典型自锁底式)进行压缩试验和跌落试验。结果进行压缩试验时,插口式盒底被破坏时仪器显示的峰值为31.2 N;压缩试验无法破坏后2种锁底结构,因此采用跌落实验,获知1-2-3锁底式被破坏时砝码质量为180 g,典型自锁底式被破坏时砝码质量为205 g。结论综合比较得知,相较于插口式,典型自锁底结构和1-2-3锁底结构的纸盒承载力优势明显,典型自锁底结构表现最强。

Carrying Capacity of the Bottom Lock Structure of Folding Carton

Objective To explore the effects of the bottom lock structure on the carrying capacity of the folding carton. Methods Three commonly used bottom lock structures ( sockets style, 1-2-3 bottom lock structure, bottom self-locking structure) were selected for compression test and drop test. Results The socket-type bottom of the box was damaged when the instrument displayed a peak of 31. 2 N during the compression test; the tensile testing machine could not destroy the latter two lock bottom structures. In the drop test, the weight of code was 180 g when the 1-2-3 bottom lock structure was damaged, and the number was 205 g when the bottom self-locking structure was damaged. Conclusion The comprehensive comparison showed that, compared to socket style, the bottom self-locking structure and the 1-2-3 bottom lock structure had obvious advantages in carrying capacity, and the bottom self-locking structure had the best performance. And an appropriate locking style could improve the capacity of sockets style.
